I don't know why you guys need to shut the engine off with the choke. I think a muck elegant idea is to cut the spark off. Look at the chain saws and weed eaters. That is the method they use. But what do I know? I am just a beginner in gas airplanes.
How do you do that from the transmitter? With a servo? An optical kill? It is an AMA requirement that you are able to kill any Gasoline engine from the transmitter. Manually grounding out the spark is not acceptable.
Do your comments also infer that the choking crowd is operating the choke manually? Just curious?
